Jack [Lemmon] challenged Tony [Curtis] to test their new [drag] disguises in public. So with the knowledge of Billy Wilder, when they arrived at the public ladies’ toilet, Jack and Tony started to pretend to fix their make-up in the mirror. Tony said: “I remember I was only doing just a little bit of mascara here and there on my eyes. Ladies were coming and going every two minutes, nobody batting an eye. I then looked at Jack through my mirror onto him and he was loving it! He was laughing and putting lipstick on and then I started laughing.” [x]
